[Feature request] Detailed Moon phase info

Hi Some astronomical data is visible under Details, but Moon phase is just too vague e.g. waning gibbous. Could you please add some more detailed (numerical) Moon phase info, e.g. age in days, and lightness in %. An it would be really cool if it could be visible in the panel as well, not only in the Detail menu after clicking on the icon. Something similar exists for Gnome in Extensions "Moon Phases". Thanks Zoltan
